Thank God I found you. You sir are a hero. You should teach at a University instead of all the professors who pretend to teach, those who go on an on for an hour complicating things and making life harder.
Thank you very much for the very nice comment, yes most things can be broken down into simpler steps.
Brian Swarthout Just one question sir: at 4:15 you say that di is between C and 2f but how can that be possible? since f = (1/2)*C ==> 2f = C, right? so you're basically saying "di is between C and C." Is this right, or am I missing something? Thank you
Al Infinity Yes, you are right, it should say di between C and f. Sorry about that, thanks for catching my error and thanks for pointing it out to me…..that must be a copy and paste error from the convex lenses where it would say the image is between f and 2f when the object is beyond 2f. Again thank you, I will add a note to the video right now.
Simply no other explanation is as clear as this one. I looked in my textbook, I looked at my teacher's notes, I looked at a few other videos, etc., but nothing compares to this one. Thank you so so so much for this video, you are absolutely amazing. I am on my way to watch a few more of your videos to clear up my understanding, and I also just subscribed! I will definitely recommend this channel to my friends. You have a gift for teaching; please don't stop! Thank you~
You're very welcome and thanks for writing such a positive comment!
It has been 10 years since this video is posted and I am here to tell that you helped people a lot and that includes me as well! you are a lifesaver thank you!
Glad I could help you and others! Thanks for your nice comment.
@@stepbystepscience are you also a Indian
Your better than our teacher and textbook combined. XD
That is a lot to be better then. Thanks for the compliment.

This was made 8 years ago but this is the only video that helps me with my physics class, you're a lifesaver, sir.
Great to hear! Thanks so much for your positive comment.

@@stepbystepsciencethis vdo uploded 10 years ago but this vdo is very helpful thank you
Present time is i am 16 years
@@stepbystepscience i am boy
I’ve spent all day trying to find a video to understand (I have a rly important text tomorrow) and you just literally saved my life
Great to hear, all the best!
thank you so much!! i've been banging my head against a wall trying to understand the logic behind ray diagrams. this is the best explanation on youtube
Glad you found the video helpful and thanks for the positive comment.
this is amazing! thank you for doing this!!! it really helped me with my test!! i received an A+!!!!!!!!!!!!!!!!!!
Absent for a day and missed an hour lecture, this dude just discussed it in 13 mins and I understood it directly.
Great and thanks for the great comment.
For some reason i dont even know why they teach us this. It doesnt even relate to something i want to do in my life
real
Im so done
Same it’s so stupid I don’t understand why we need to learn the measurements of an image reflecting off a mirror 💀

Goodness gosh! I really didn't knew that the way how the convex lens and concave mirrors form the images in the same manner till now! Thank you so much and that was so helpful rather than studying 10 different ray diagrams!!
You're very welcome. Happy to help!
How you get that emoji
Thanks a lot Sir 🥰
Love from kerala, India❣️
You're welcome. Love from Berlin back to India!
I've been looking for a decent resource on this for days and this is the first time I've actually seen the effects compared based on the position of the image. I cannot thank you enough, I wish that one day an $80 text book would be half as good as your explanations.
Thanks so much for the nice feedback and glad you found what you needed
I have a quiz tomorrow in physics and this really helps! Thank you for making it so easy to understand!
It's been 11 years since this was posted, and I'm still using it! Thanks a lot!
Great to hear it's still helpful!
Thank you so much I understood it just in a few minutes rather than my teacher teaching for 2 hours.
Great and thanks for watching and leaving a comment.
I was falling behind in Physics for a couple of months and then I found your channel and I honestly couldn't be more thankful. This is one of the most helpful videos on here, and I'm doing good in physics altogether. Thanks a lot!
Thanks for you comments, glad that physics is going well.
Immediately clear and effective explanation! I watched some other videos on the same concept and was still confused, but this was the exception for me. Also, I appreciate the length. Some videos are ~15-20min, which can take a lot of time. Thanks for the help!
hapamateo thank you for the very nice comment, yes I try to keep them all under 10 minutes. I try to get right to the point no sense going on about nothing just to hear yourself talk.
thank u for explaining this to me like a toddler. u taught me everything i need to know for my exam in 12 minutes that my teacher failed to teach me in 2 weeks. very helpful!
Glad I could help and best of luck on the exam!
this dude gave me answer to my homework bro word for word.. thnks dude...
No problem, glad that you found the video helpful.
Thank you so much....helped me in Ray diagrams which I couldn't understand for months, have an exam tomorrow!!! You are a saviour 💖✨
Glad it helped! Good luck on the exam!
@@stepbystepscience Thank you so much exam went really well ✨
your teaching is excellent ... this the first time I watch your video
all I can say .....it's very simple an easy to understand much better than my teacher who has complicated things
keep up hero
Thank you very much for the positive comment.
I learned more after watching 5 minutes of this video than the past week in class. Thank you so much!!!!
Very nice of you to say!
Great that test went well, thanks for the comment.

THANK YOU. Esp for what you pointed out at 11:02, I did not realise it at all. Blew my mind. Thank you so much!!
Yes, it had the same effect on me when I realized it for the first time. Thanks for the comment.
I never thought that i will use youtube for studies😂
Btw very helpful thanks🙌🏻
Excellent, thanks for the comment.

Thank u very much...
You explain better than my school...
You saved me before my exam....thank u again a lot...now i can get more videos from your channel regarding physics
Thank you so much! I finally understood this after so many days of struggling to find the right way to learn
You are very welcome, great that you found the video helpful.
THIS! YOU EXPLAINED THIS SO WELL! Just got out of my class and this is all my professor had to say!!!! Lol
So glad the video was helpful!
when you go into a test knowing more than you need to know
That is a great comment, thanks for watching.
Pip
and I love that lol
Hey sir I am a 10 student from India a far away you but I can hear you, understand you , respect you because I dont know who are you and from but you teach me
you are really good!!!!
Thank you so much!!
thank you so much for this, it helped me out a lot! i don't understand my teacher because he talks too fast and he's not very good at explaining things, so i've resorted to youtube for help, and your videos are perfect because they give a really good explanation of the concepts and you make it really easy to undertand. thank you so much!
Great that you have found the videos helpful and thank you so much for taking the time to comment.
Thank you sir I understand light and optics very well thanks to you! Now I can get an A+
Great and I hope you do!
i honestly didnt listen to my sci teacher because she was so boring to listen to and she was practically talking to the white board. thank you for this video !
You are very welcome.
thanks...it helped me alot for my test.. :-)

Thank you, one can only try.
but why the line doesn't point in the middle of "F"?? in 2?
You, sir, are a most helpful human being.
@korikafez can't ask for more then that, thanks for the positive comment.
Thank you so much.It helped me a lot.
Thank you so much! This was great. My physics prof is so boring and slow talking that he puts me to sleep. He needs to use something else other than just a projector to explain something like this. He needs to make things come alive. Thank you again, because I got it!!!! Off to the final!
I hope the final went well!
Thanks sir only now I understood that we have to understand physics instead of memorising.
Yes, it is better to try to work out a picture in your mind where everything fits together.
Best video on UA-cam for this topic
Thanks so much!
THANK YOU SO MUCHHHH!! I HATE MY TEACHER AND YOU TEACH WAY MORE BETTER THAN HIM. IF I WERE A SCHOOL PRINCIPAL I WOULD HIRE YOU!!!
I'll sent you my application. You are very welcome, thank you very much for watching and commenting.
This video was the best video about convex lens that I found in youtube...(helped me a lot..I was sooo confused with this topic)🙂
Thanks for the very positive comment.
Love this video! Just wanted to point out though that in scenario 1 (do>C), you mentioned that di is between C & 2f. However, in the diagram you have it between C & f (and also you mentioned that C=2f) so I think that was a typo!
Ya
This video saved my grade, thank you so much!
You're welcome. Glad it helped!

Thanks for the comment and I hope the exams go well.
I wish you were my physics teacher for the year
Thank you sir for your teachings as only because of you I could understand these diagrams. I could score good only because you made it simple for me to remember, many tried but failed and in the end it was you who could tell in such a easier manner. Sir because of you and these diagrams I could score more than I could except.
Thank you so much.
You are very welcome and thank you so much for leaving such great comment.
what happens to the size and location of the image when you bring the flashlight nearer to the concave mirror?
+brylle dave As the object get closer, the image gets bigger and farther away.

Thank you sir, I have a test coming up tomorrow, this video help me a lot 😭😭
Best of luck on the test!
Sir can you pls tell me that how to draw a ray diagram for convex lens whet the object is at infinity ?

Thank you so much, this helps a lot, I now know very much about concave and convex. I'm a junior in high school taking honors physics, this is great. I don't understand it much when I'm in school but you made me understand it in 10 minutes! Once again thank you

But what is the focus???
Where the light rays come together, are focused. You can also see a listing of all my videos by topic at www.stepbystepscience.com
BTS A.R.M.Y you probably not have taught physics so you are saying it. The focus is a point where the light rays combine together at a point.
BTS A.R.M.Y well focus is that point were the ray which is parallel to principal axis will reflect at!!!!!.....so every ray parallel to principal axis will reflect at point f (Focus
ua-cam.com/video/ExM0IrRnMSA/v-deo.html
Please watch to clear all the doubts
focus is a point at which light rays pass after the reflection when it incident parralel to the principle axis
yooo, thank you for this. I'm struggling with our lesson and gladly i played this and got it somehow.
Glad I could help!
My physics teacher had me watch this for homework.........I actually understand it now! Thanks!
